Abstract: The content of organic matter in river sediment is high, which pollutes water body and easily causes secondary pollution. In order to make harmless use of sediment, the river sediment was used as raw materials to prepare the ecological restoration base material, and the preparation technology and performance of the base material were discussed. The results showed that the optimal ratio was cement 5%, sediment 14%, sandy loam 73%, straw pulverized material 2%, water 4% and bacterial liquid 2%. The flexural strength, compressive strength, porosity and water absorption of the ecological remediation base material were 0.65 MPa, 1.185 MPa, 17.46% and 13%, which had certain strength and could be used for slope protection and met the nutritional needs of plant growth.

Key words: sriver sediment, ecological restoration base material, characteristic, slope protection
